Specification of Letters Patent.

' Patented Feb. 15, 1916.

Application filed March 1, 1915. 1 Serial 1V0. 11,286.

To all whom t'tmag concern? i V Be it known that we, lVILLIAM WEGK- wER'rH and FRED C. CONRAD, citizens of the United States, residing at Hoquiam, in the county of Chehalis and State of VVashington, have invented certain new and useful Improvements in Lubricators, of which the following is a spec1ficat1on,-reference being had to the accompanying drawings. V

This invention relates to new and useful improvements in lubricating devices and more particularly to what is known. in this art as gravity feed lubricators, the main object of the present invention being the provision of a lubricator consisting of a body having therein a tube which extends beneath the body and is provided therein with awick extending through the tube and into the body which contains the lubricant, thus conveying the lubricant from the body down through the tube, on to the parts to be lubricated.

Another object of the present invention, is the provision of a device of the, above character which will possess advantages. in points of efficiency and durability, is inexpensive to manufacture and, at the same time, is simple in construction and operation.

lVith the above and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts as will behereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming'a part of this application, Figure 1 1s a side elevation of a lubricator constructed in accordance with our invention. Fig. 21s a longitudinal sectlonal view of the same; and

Fig. 3 is a detail perspective view of the wick supporting member. v

In carrying out our invention, we provide a cylindrical body member 1 which is formed of sheet metal and is provided with an open upper end. Extending through the inner end of the body, centrally thereof,,is a discharge pipe 2, one end of'said pipe extending outwardly beyond the bottom of the body 1, while the other end thereof extends into the body a suitable distance. The upper edge of the body 1 is provided with a bead; ing upon its outer face, as shown at 3,fthe purpose of which will be hereinafter more fully-set forth.

Removably arranged upon the upper open end of the body 1, is a cover t-having a downwardly-depending annular flange 5 adapted to be inserted-withinthe upper open end of the body and extending outwardly beyond the flange'5', is a horizontal flange 6 WhlCh' is adapted to bear. upon the upper edge of the body-1 and the beading 3 to support this cover 41in its operative orclosed position. From thisit will be apparent that i 7' when it is desired to fill the cylindrical body 1 with the "lubricant, the cover 4: can bequickly and readily removed by engaging an instrumentbeneath the flange 6. Extending through the tube 2, is a wick 7, theone end of which projects slightly beyond the outer endof the tube 2, while the inner end thereof extends into the body of the cylinder lfto absorbthe lubricant therein and by capilorlower end of the tube; where it is de-' posited on the parts to be lubricated.

Upon the inner or upper'end of the tube 2, we have provided a sleeve 3 and formed integral with this sleeve, is an arcuate extension 9 which is preferably U-shaped in cross section and which forms a support for the wick as it passes into the upper end of the tube 2, thus preventing the wiek'from cramping or bending, which would stop the flow. of the lubricant. The tube or'pipe 2 is provided adjacent its outer or lower-end with a slot 10 whereby a sharp instrument may be inserted therethrough when it is desired to pull the wick out as it wears off" at the outer end thereof. r From the above description taken in con- 7 nection with the accompanying drawing, it

will be readily apparent that in placing our lmproved lubrlcator 1n position, the body 1 is supported upon the bearing and the tube 2 extended into the bearing so that the wick 'will engage the surface to be lubricated.

, lary attraction, carry the same to the outer The body 1 is then filled with a lubricant,

any form of oil being used, and as the pipe 2 extends downwardly below the body 1, the capillary attraction will cause the oil to pass downwardly through the wick 7 on to the parts which are to be'lubricated. It will also be noted that by having the extension '9 of the sleeve 8 arcuate in form, it will prevent the wick from becoming cramped or-from bending, so as to prevent the flow of oil through the wick. It will also'be apparent that our device is extremely simple in constructionand can be manufactured and placed upon the market at a comparatively low cost.

obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying our invention into practice, Withoutsacrificing any of the novel features or departing from the scope of the invention, as defined by the appended claims. I

Having thus described our invention, What We desire to claim as new and secure by Letters Patent, is: r r

l. A lubricator including a body having an open upper end, a. beading extending around the open end thereof, a cover having a downwardly depending flange adapted to extend in the body, a horizontal flange adapted to engage over the beading to support the cover, a tube extending centrally through the bottom of the body, said tube extending into the body .at apoint adjacent the top thereof, a sleeve upon the upper end of the tube, an arcuate supporting arm substantially Urshaped in cross section formed integral With said sleeve, and a Wick arranged Within the body and extending down through the tube, said wick being adapted to be arranged over the arcuate supporting arm, and for the purpose set forth.

2. A lubricator including a. bodyhaving an open upper end, a beading extending around the open end thereof, a cover having a downwardly depending flange adapted to Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

stantially U-chaped in cross section formed integral with said sleeve, and a Wick arranged Within the body-and extending down through the tube, said Wick being adapted to be arranged over the arcuate supporting arm, and said tube being provided with an elongated slot at a point adjacent its lower end, whereby an instrument .may be in serted therethrough to adjust the Wick With- J in the tube.

3. A device of the character described including a container, a tube extending into one end oi' the container, awvick arrange within the tube, and a \viclrsupport disposed 7 at the inner-enchof the tube and including a 'adially extending outwardly and 1 down- Wardly curved Wick supporting arm, the

arm being'transversely curved to form a.

seat for the Wick.
